GAS EVACUATION METHOD FOR DISCONNECTED SECTION OF GAS PIPELINE

摘要

FIELD: oil and gas industry.SUBSTANCE: method includes delivery of gas to nozzle of gas ejector and gas evacuation by this gas ejector from disconnected section of pipeline to parallel line or section next to the disconnected one, at that to the from disconnected section of pipeline fluid-gas ejector is coupled additionally and its nozzle is communicated with fluid pump, while output of fluid-gas ejector through separator is communicated to parallel line of gas pipeline or section of gas pipeline next to the disconnected section. Input to fluid pump is communicated with a vessel with fluid placed under separator, thereafter as evacuation intensity decreases gas ejector is switched off and gas evacuation from the disconnected section is made by fluid-gas ejector switching on delivery of fluid to its nozzle.EFFECT: ensuring complete gas evacuation from the disconnected section.1 dwg
